I-SIS(Styrene-isoprene-styrene block copolymer)
I-Baling Petrochemical SIS yi-styrene - i-isoprene block copolymer ngendlela ye-particle porous emhlophe okanye i-translucent compact particle, eneempawu ze-thermo-plasticity enhle, i-elasticity ephezulu, i-melt melt fluidity, ukuhambelana kakuhle kunye ne-resin tackifying, ekhuselekileyo kunye ne-non-toxic.Inokuthi isetyenziswe kwizinto ezincamathelayo ezinoxinzelelo olushushu olunyibilikayo, isamente ezinyibilikayo, iipleyiti zokuprinta eziguquguqukayo, iiplastiki kunye nokuguqulwa kwe-asphalt, kwaye yeyona nto ilungileyo yezinto ezincamathelayo ezisetyenziselwa ukwenza iingxowa zokupakisha, izixhobo zococeko, iiteyiphu ezincamathelayo ezinamacala amabini kunye neelebhile. .
IIPROPATI KUNYE NESICELO
I-Styrene-isoprene block copolymers (SIS) ngumthamo omkhulu, i-elastomers ye-thermoplastic enexabiso eliphantsi (i-TPE) eveliswa yi-ionic copolymerization ephilayo ngokuzisa ngokulandelelana i-styrene, i-2-methyl-1,3-butadiene (isoprene), kunye ne-styrene kwi-reactor. .Umxholo we-styrene ngokuqhelekileyo uhluka phakathi kwe-15 kunye ne-40 ekhulwini.Xa zipholile ngaphantsi kwendawo yokunyibilika, ii-SIS's ezinomxholo we-styrene ophantsi wesigaba-ukwahlula kwi-nano-ubungakanani be-polystyrene spheres ezifakwe kwi-isoprene matrix ngelixa ukwanda komxholo we-styrene kukhokelela kwi-cylindrical kunye ne-lamellar izakhiwo.Imimandla enzima ye-styrene isebenza njenge-crosslinks ebonakalayo enika amandla omatshini kunye nokuphucula ukuxhathisa kwe-abrasion, ngelixa i-matrix ye-rubber ye-isoprene inikeza ukuguquguquka kunye nokuqina.Iimpawu zomatshini we-SIS elastomers kunye nomxholo ophantsi we-styrene zifana nezo zerubha ezixutywe.Nangona kunjalo, ngokungafaniyo nerabha ekhutshiweyo, ii-elastomer ze-SIS zinokusetyenzwa ngezixhobo ezisetyenziselwa ukwenza iipholima ze-thermoplastic.
I-SIS block copolymers zihlala zixutywa kunye ne-tackifier resins, i-oyile kunye nezihluzi, ezivumela ukuguqulwa okuguquguqukayo kweempawu zemveliso okanye zongezwa kwezinye iipolymers ze-thermoplastic ukunyusa ukusebenza kwazo.
I-SIS copolymers isetyenziswa kakhulu kwi-adhesives ye-hotmelt, i-sealants, imathiriyeli ye-gasket, iibhanti zerabha, iimveliso zokudlala, iipali zezihlangu kunye neemveliso zebhitumene zokuvula indlela kunye nokufakwa kophahla.Zikwasetyenziswa njengeemodyuli zempembelelo kunye ne-tougheners kwiiplastiki kunye (nezakhiwo) zokunamathela.
